Jamie Crisalli writes gritty melodrama and bloody combat. Fascinated with skulls, rivets and general gloominess, when she was introduced to the Warhammer universes, it was a natural fit. Her work for Black Library includes the short stories 'Ties of Blood' and 'The Serpent's Bargain', and the forthcoming Age of Sigmar novella The Measure of Iron. She has accumulated a frightful amount of monsters, ordnance and tiny soldiery over the years, not to mention books and role-playing games. Currently, she lives with her husband in a land of endless grey drizzle. Graeme Lyon is the author of the Age of Sigmar novella Code of the Skies and the Space Marine Battles novella Armour of Faith. He has also written a host of Warhammer 40,000, Warhammer Age of Sigmar and Warhammer short stories including 'The Carnac Campaign: Sky Hunter', 'Kor'sarro Khan: Huntmaster', 'Black Iron', 'The Eighth Victory', 'The Sacrifice' and 'Bride of Khaine'.
